(54) Shift controlling apparatus for continuously variable transmission


(57) A shift controlling apparatus for a continuously variable transmission changing of an input side rotational element driven by an engine via a power transmitting element to an output side rotational element, has, a rapid acceleration determination unit for determining whether or not a rapid acceleration demanding condition according to the depressed amount of an accelerator pedal, basic shift mode setting unit for setting a rotating speed of the input side rotational element based on a basic shift mode according to operating conditions such as throttle opening, vehicle speed and engine speed, accelerating shift mode setting unit for increasing the vehicle speed based on an accelerating shift mode correspondingly to an increase in engine speed, and a control unit for switching from the basic shift mode to the accelerating shift mode when the rapid acceleration determination unit determines that a rapid acceleration demanding condition occurs.
